History

020 replaced the 0171 and 0181 codes on 22 April 2000, after a period of dual-running which began 1 June 1999. Before May 1990 there had been a single area code of 01 which covered the same area as the current 020 code. Before this date the three digits after the code indicated the geographic area the number was located. e.g. 01-222 1234 was a number in Westminster, and 01-946 1234 was in Wimbledon. However, more than one sub-code was usually overlaid for each area such that all Wimbledon numbers did not necessarily begin 01-946. April 22 is the 112th day of the year in the Gregorian calendar (113th in leap years). ... This article is about the year 2000. ... June 1 is the 152nd day of the year in the Gregorian calendar (153rd in leap years), with 213 days remaining. ... 1999 (MCMXCIX) was a common year starting on Friday, and was designated the International Year of Older Persons by the United Nations. ...

Between 1922 and 1966 the three digit sub-codes each corresponded to one area and were represented by letters by way of a mnemonic. The first exchange to become part of the London Director telephone system was Holborn. The numbers were written as ABBey 1234 and WIMbledon 1234. The system of mnemonics was withdrawn with the transition to all-figure dialling. Image File history File links History_of_london_std_codes. ...
